DUPLICATING-MAGHINE.

Specification of Letters Patent.

Patented Aug. 10, 1915.

Application filed January 4,1913. Serial No. 740,222.

To aZZ whom it may concern Be it known that I, Gnoncn ARTHUR VVIL- LIAMRUsHwoR'rH, a British subject, resid- Lancaster, England, have inventedcertain new and useful Improvements in Duplicating-Machines, of whichthe following is a specification.

This invention relates to duplicating machines, more particularly tothose in which a number of sheets are printed off by means of a waxstencil mounted upon a cylinder or by means of lines or blocks of typemounted upon a cylinder orv in which a duplicate of a letter is taken byimpression upon a damp sheet passing between rollers.

In the stencil-carrying machines, it is customary to print in two ormore colors by applying pads of different colors to the stencil-carryingcylinder, usually a difi'erent color being employed for .the heading orsignature from that employed for the body of the circular or letter.

In type-carrying machines it has been proposed to print in more than onecolor by an additional roller.

This invention is designed to provide mechanism for printing upon eachsheet of paper an impression in the same color as or a diiferent colorfrom the impression printed by the cylinder or bed, so that while acircular letter may be printed with the signature (either in the same ora diflerent color) from the rotating cylinder or bed, the description ofthe person signing or the name of thefirm or both may be printed in suchposition that the signature, when printed from the cylinder or bed, willlie adjacent thereto, preferably all'three in diflerent colors.

It consists essentially of an oscillating or reciprocating printingstamp or device mounted upon the frame of the machine, to which stamp ordevice a downward movement is imparted to print an impression on thepaper before being drawn forward by the machine, preferably during suchperiod of the rotation of the cylinder as the paper is at rest.

The invention will be fully described with reference to the accompanyingdrawmgs.

Figure 1 is a side elevation of a stencilcarrying machine showing theinvention applied thereto. Fig. 2 is a similar side elevation showingthe position of the parts when Manchester, county of in operation. Fig.8 is a side elevation of certain parts immediately before 1 beingbrought into position. of the machine with the stencil-carrying cylinderremoved. Fig. 5 is a side elevation of a type-carrying machine showingthe invention applied thereto.

Referring to said drawing the invention is shown applied to aduplicating machine with a cylinder A carrying either a stencil or type.The machine is constructed in the ordinary way with the rotaryduplicating cylinder A mounted in a frame B and rotated by a handle C,and a paper feed board At the intake or feed end of the machine, aprinting stamp. E is mounted above the paper feed board D, which stampcan be operated while the sheets of paper are at rest. The printingstamp E is of rubber, metal, wood or composition and is mounted in aframee in which it can reciprocate and be pressed down upon the piece ofpaper to be printed, (being preferably of the type of stamp known as aturnover or similar self-inking stamp).

The printing stamp E is mounted in a horizontal frame F which rests uponthe pile of paper sheets and from underneath which the top sheet istaken at each revolution of the printing cylinder A.

The stamp is capable of adjustment longitudinally of frame F, owing tothe engage ment of the ends of thecross-bar with the bars 7, whichlatter are arranged longitudinally of the machine and are disposed abovethe side members of said frame, and it can also be adjusted transverselyby moving the secondary frame F toward either side of the machine, thisframe F being secured to cross-bar f and having a portion thereofengaged with the longitudinal slot f in said cross-bar. The depressionof the stamp causes it to print on the surface of the paper.

The stamp E is operated at every revolution of the printing cylinder bylevers G and cross bar H. The position of the bar H is adjustable,sothat it may be set to correspond with the position of the printingstamp E.

In the arrangement shown'in Figs. 1 to 4, the levers G are raised by apin 9 fitted into one of the gear wheels, which pin en gages a link orconnecting rod 9 pivoted to the lever G at one side of the cylinder. As

Fig. 4 is a plan view the machine is rotated the pin g engages a notchin the end of the link g, and said link is raised thereby and stretchesthe spring 9 As the pin 9 is rotated, the movement of the link g isarrested by the frame B of the machine, and the pin 9 disengages itselftherefrom, allowing the levers G to be drawn sharply back by the spring9 the cross bar H striking the head of the printing stamp E and forcingthe latter downward into contact with the paper to impart the desiredimpression thereon.

In the arrangement shown in Fig. 5, the pin 9 is fitted to the side ofthe cylinder, and a cam g is attached to the lever Gr. As the pindescends, it engages the cam g and forces the lever G downward, bringingthe cross bar H into contact with the head of the printing stamp E andforcing the stamp downward into contact with the paper to impart thedesired impression thereon.

v To compensate for the varying thickness of the pile of paper sheets,the lever G is made in two parts or lengths hinged together at 9*. witha spring 9 to hold the two parts of the lever in normal position. Alever constructed and actuated in a similar manner may be applied to themachine shown in Fig. 1. V

What I claim as my invention and desire to protect by Letters Patentis 1. In a duplicating machine, the combination, with a feed table; of aframe mounted thereon and embodying a pair of spaced, parallellongitudinal bars, and a slidable cross-bar connecting the first-namedbars; a secondary frame adjustable toward either end of said cross-bar;and a stamp mounted in said secondary frame.

2. In a duplicating machine, the combination, with a feed table, arotary printing cylinder, and gearing for driving said cylinder, oneelement of said gearing being provided with a pin; of a depressibleprinting stamp mounted on said table; a reciprocatory element adapted tostrike downwardly upon Copies of this patent may be obtained for thehead of said stamp, to actuate the latter; and a member carried by saidelement for periodic engagement and release by said pin.

3. In a duplicating machine, the combination, with a feed table, arotary printing cylinder, and gearing for driving said cylinder, oneelement of said gearing being provided with a pin; of a depressibleprinting stamp mounted on said table; a reciprocatory element foroperating said stamp embodying a spring controlled lever provided with amember adapted to strike downwardly upon the head of said stamp; and amember carried by said lever for periodic engagement and release by saidpin.

4. In a duplicating machine, the combination, with a feed table, arotary printing cylinder, and gearing for driving said cylinder, oneelement of said gearing being provided with a pin; of a depressibleprinting stamp mounted on said table; a reciprocatory element adapted tostrike downwardly upon the head of said stamp, to actuate the latter;and a link pivoted to said element and provided with a notch adapted toperiodically receive said pin. 7

5. In a duplicating machine, the combination, with a feed table, arotary printing cylinder, and gearing for driving said cylinder, oneelement of said gearing being provided with a pin; of a depressibleprinting stamp mounted'on said table; a reciprocatory element foroperating said stamp embodying a springcontrolled lever provided with amember adapted to strike downwardlyupon the head of said stamp; and alink pivoted to said lever and provided with a notch adapted toperiodically receive said pin.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit IIQSSQS.
